SASH-PU LLEY.

SPECIFICATION forming part of Letters Patent No. 647,842, dated April17, 1900.

Application filed August 4, 1899. Serial No. 726,091. (No model.)

To all whom it may concern:

Be it known that'I, WARREN T. KELLOGG, of the village of Lansingburg,county of Itemsselaer, and State of New York, have invented new anduseful Improvements in Sash-Pulleys, of which the following is aspecification.

My invention relates to that class of sashpulleys in which the cases orbody parts are made from a stampedout plate of sheet metal; and myimprovements upon this class of a lip formed on the inner opposite edgesof the latter at its top, and a lip formed on each of the opposite sidesof the pulley-passage formed in the face-plate, and the latter havingblades at each of its corners adapted to enter the wood when thesash-pulley is driven into its socket in the sash, and thus dispensewith nails and screws thereat.

Accompanying this specification to form a part of it there is a plate ofdrawings containing six figures, illustrating my invention inapplication, with the same designation of parts by letter-reference usedin all of them.

Of the illustrations, Figure 1 shows a plan view of the plate from whichthe pulley case or body is made. Fig. 2 is a top view of thesash-pulley, shown as inserted in a socket formed in a block of wood andas made without a face-plate. Fig. 3 is a plan View of the plate ofsheet metal from which the faceplate is formed and bent into shape. Fig.4- is a side elevation of the sash-pulley and combined face-plate. Fig.5 is a section taken on the line w a; of Fig. 4. Fig. 6 is a top view ofthe combined sash-pulley and face-plate, shown as inserted in a socketformed in a block of wood.

The several parts of the sash-pulley and face-plate thus illustrated aredesignated by letter-reference, and the function of the parts isdescribed as follows:

I The letter P designates a plate that is stamped from a piece ofsheet-steel or other sheet metal, and the letters 19 p designateprojections on what is the upper edge of the plate when bent into shape,and which pro jections, after the case has been formed, are bentinwardly from each of the opposite sides of the case to be at rightangles to the sides of the latter, and thus form the lips L of the case.

The letters R designate convexities, which are rounded outwardly fromthe sides of the body part or case, and each of these convexities isprovided with a blade or rib 7, projected from its outer side at itstop.

The letters E E designate the ends of the plate P, and these ends,whenthe plate is bent into shape to form the body part or case, are

so arranged as to lap past each other at one of the pulley-case sides,as shown at Fig. 2.

The letter S designates the pulley-axle on which the pulley proper, W,is mounted to turn. Where the axle extends beyond the case through thelapping ends E E it is at h riveted to hold the overlapping ends asconnected, and the other end of the axle where extending beyond theopposite side of the case at 72 is also riveted or headed, thus givingto a pulley-case made from sheet metal all that advantage which comesfrom having solid ends and the strength which the latter have When beingdriven into a socket.

The letter F designates the face plate, which is shown in the blank orsheet form at Fig. 3, and as bent into shape and combined with the bodypart or case at Figs. 4, 5, and 6.

The letters 19 p designate lip-forming projections which are constructedon the inner and opposite sides of the openingO made in the face-platefor the pulley W. Each of these projections 192 is made wide enough onits inward projection from the sides of the opening to be turneddownwardly and laterally, as lips L each adapted to underlap and hold asgrasped one of the lips L of the body part within its infold. As thusconstructed and arranged the three thicknesses of metal formed by theoverlapping and underlapping lip L of the face-plate and theintermediatelygrasped lip L of the body part at each side of the latterserve to strengthen the case, so that when driven into a socket the sidewalls of the case will not be sprung inwardlyso as V to interfere withthe working of the pulley.

The letters f f designate projections that are formed on the edge of theplate F at all of its corners, and the letters f designate the edge ofthe plate at each side where between the projections f being shaped forconnection, these corners f where projecting, as well as the edge of theplate F, where betweenthe corners, as indicated' at f are turned down,so as to be at right angles to the top of the face-plate, and thus theprojections f form blades f ,of which there are two at each end of theplate. When the connected face-plate and case or body part are beinginserted in a socket formed in a window-sash, the blades f are-driveninto the wood for the purpose of connection, thus dispensing with theuse of nails or screws.

Apart from the manner of constructing the face-plate with the blades fand the manner of constructing them to connect with the cases I make noclaim; I am also aware that the convexities R and the ribs r are old andwellknown features of sash-pulley construction.

Inasmuch as my i mpro ved pulley-case made fromsheet metal with solidends and with the lapping ends of the bent sheet metal secured wherelapping past each other at one of the case sides bya riveting-headformed on the axle could be used without a face-plate, I do not limit myinvention as relating to the construction of the pulley-case to itscombina tion with a face-plate; neither do I limit my improvedconstruction of a pulley face-plate having the blade form corners andthe lips on the inner edge of the pulley-opening to connectwith the lipson the case to their combination with the pulley-case which I illustrateit connected.

Having thus described myinvention, what I-claim, and desire to secure byLetters Patent is- I 1: A sash-pulley case made from a piece of sheetmetal bent to form the case or body part When the face-plate is.

- written.

with solid ends; with the ends of the plate lapping past each otheratone of.the case or body sides; and having'a pulley-axle pro vided witha riveting-head at each end; with one of the riveting-heads passedthrough the lapping ends ofthe plate, and thereat riveted,

and the other head passed through the opposite side of the body or caseand thereat riveted, substantially as. and for the purposes set forth.

2. In a sash-pulley the combination with a caseor body part having aninturned lip or projection on each of the opposite edges of its 'top; ofa face-plate having lips projected inwardly from each of the oppositesides of the pulley-passage, with each of such last-named lips adaptedto be turned downwardly and laterally-to underlap and grasp one of thelips or projections formed on the case or body part, and with the endsof the-fac'e-plate at each of its corners provided with a downturnedblade, whereby when the case is driven into a socket each of the bladeswill enter the wood, and hold the parts as connected, substantially asshown and described. 7

3. The combination with a sash-pulley case made from a piece of sheetmetal and bent to form the case with solid ends, and having a -lipprojecting inwardly from what are each of the opposite sides of the casewhen bent into shape; and a face-plate provided with a central openinghaving a lip projected inwardly from each of its opposite sides andthereat arranged to be bent downwardly and laterally to underlap andgrasp one of the lips of the body part or case, substantially as shownand described.

Signed at the city of Troy, New York, this 31st day of July, 1899, andin the presence ofthe two witnesses whose names are hereto WARREN, T,KELLOGG.
